BMW 330-i975 viewsIt used to be a oil filter.... POOR ENGINE. Not from the Ferrari behind...By the way our oil change is NOT only an oil change it's a small service :check all the fluid levels (except automatic transmissions without dipstick) top-up as needed,check all the tire pressures and inspect the vehicle visually, safety items like wiper blades lights and so on. This is the bare minimum you should do as periodic maintenance or car care.

Oil Filter Disintegration Example960 viewsSo ,as you can see ,oil filter quality does matter,there are only three original oil filter manufacturers for this cars : MANN (MANN &Hummel) or Hengst ,both German and Knecht-Mahle which is Austrian equivalent of MANN filters .We like all of them since they're the best what money can buy ,they all very high quality and made very precisely,by the way most of the time they also make the actual housing/casting for the oil filter.
